IMPROVEMENT IN METALLIC ROOFINGS.

Specification forming part of Letters Patent No. 146,130, dated January6, 1874; application filed 1 December 5,1873.

To all whom it may concern:

Be it known that I, ANTOINE GATEAU, of

Chicago, in the county of Cook and State of Illinois, have invented anew, useful, and Improved Metallic Roofing, of which the following is afull, clear, and exact description, which will enable others skilled inthe art to which my invention appertains to make and use the same,reference being had to the accompanying drawing forming a part hereof,and in which- Figure 1 represents a front elevation of a portion of amansard roof provided with my improved roofing; Fig. 2, a top view ofone of the sheets detached; Fig. 3, a cross-section in the plane of theline w x, and Fig. 4 a longitudinal section in the plane of the line yy.

Like letters of reference indicate like parts. The object of myinvention is to make a rich and ornamental metallic roofing, which maybe applied without solder, and'which will be watertight and fire-proof.In order to accomplish this object, my invention consists in certainnovel features, hereinafter fully described and particularly set forth,relating to the construction of the sheets employed in the formation ofthe roofing.

In the drawing, A represents a portion of a mansard roof; and this formof roof is shown for the reason that my improved roofing may be appliedto a steep roof with the greatest advantage. B B are the sheets of whichthe roofing is made. These sheets are made of sheet metal, preferably ofzinc. c a are nailholes or screw holes in the upper part of each sheet,for the purpose of enabling the sheets to be attached to the roof bymeans of nails or screws arranged in these holes. That part of the sheetwhich surrounds the holes a a may be flat, as shown, and rest upon theroof. The holes a a, however, are not essential, for nails may be driventhrough the The remaining part of the sheet is stamped up or raised, asshown, the edges projecting downward, so as to rest upon the roof. A11air-space is thus made between each sheet and the roof. 0 is a tongue,pro jecting laterally from each sheet; and c is a ridge, in which thepart 0 terminates, this ridge being stamped or raised up from said part.The bottom of each sheet is preferably curved, as shown; and c c arecurved ridges raised from the upper part of the sheets. C is a raisedridge, terminating in one of the ridges c c, and lying opposite theridge 0.

e is a hole in the lower wall of a small box or compartment, otherwiseclosed and watertight, in the lower end of the ridge 0; and e is a pin,of such a size as to readily enter the hole e, and projecting upwardfrom the lower end of the under side of each sheet, as shown in Fig. 4..

In arranging the sheets B B together to form a roofing, a number areplaced together side by side, as shown in Fig. 1, so that the ridge 0 oneach sheet will be lapped by the opposite side of each other sheet. Thisseries of sheets is fastened to the roof, and an upper series is thenarranged on the roof so that each sheet therein will lap two of thesheets in the next lower series, and so that the lower end of each uppersheet will sit over one of the ridges c c of each lower sheet lapped byit, the pin 0 being first inserted into the hole 0, so that the lowerend of each upper sheet will be thereby helddown. In-

stead, however, of holding the lower ends of the sheets down by means ofthe pin 6 and hole 6, they may be nailed or screwed down. As fast aseach series is arranged upon the roof in the manner described, the topof each sheet is also fastened to the roof, and this process iscontinued until the roof is covered.

Any suitable cornice, coping, or angleboards may be employed inconnection with this roofing.

It will be perceived, from the foregoing description, that each upperseries or row of sheets will break joints with each lower series or row;that the ridges c c and 0 prevent a lateral flow or drift of water orsnow, which would result in leakage and that the ridges c c prevent avertical or upward flow or drift.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The raised sheets B B, provided with the .raised ridges c, O, and ac, and constructed substantially as shown and described, and for l thepurposes set forth.

' 2. The raised sheets B B, provided with the raised ridges c, O, and cc, and with the openings, e and pin e, substantially as shown anddescribed, and forthe purposes set forth.
